WASHINGTON – President Bush yesterday presided over the heartwarming citizenship ceremony of Brooklyn-raised Spc. Noe Santos-Dilone – and moments later pinned the Purple Heart to the wounded Army warrior’s chest.

“Today is a great day to be a soldier in the U.S. Army,” a moist-eyed Santos-Dilone, 21, told The Post.

“I’m so proud to be a citizen – and I never dreamed the president would be standing with me when it happened,” the Dominican Republic native said.

Santos-Dilone, who came to Brooklyn as a 10-year-old in 1995, lost his left leg in Iraq last September.

Standing on crutches, he raised his right hand and took the citizenship oath during a ceremony at Walter Reed Army Medical Center – and quickly received a handshake and pat on the back from a beaming Bush.

The president playfully recounted the first time he met Santos-Dilone at the National Hispanic Prayer Breakfast in Washington last month.

“I was working the rope line. He grabbed my hand and he said, ‘I’m not a citizen of the United States and I want to be one,’ ” Bush recalled.

“Now, here’s a man who knows how to take it directly to the top,” Bush said as the crowd erupted in laughter.

During the Purple Heart procession that followed, Santos-Dilone playfully quipped to the president, “It’s good to see you again,” prompting Bush to joke back, “Hey, I see you everywhere,” the soldier recounted.
